Abstract
Supercontinuum (SC) generation using multiple thin plates is demonstrated with a femtosecond laser pulse. We propose an improved technique to obtain larger spectrum broadening and higher spectral intensity by employing mixed multiple thin plates with different thicknesses and materials. Furthermore, the spectrum has good stability, which is superior to that of the spectrum induced by the traditional single filament in bulk material. Our approach offers a route towards simple and stable SC generation for potential applications.
Highlights
Seven 120 μm thin fused silica plates were applied for SC generation
We have demonstrated a technique using multiple thin plates to generate4.a Conclusions more intense and broader SC spectrum. This is achieved by a set of solid thin plates with different thicknesses materials
